My Emacs 24.5.1 is not responding frequently recently on my MacBook Pro Yosemite 10.10.3. I have installed it from emacs for mac osx. Emacs window does not open, it shows Not Responding in the Activity Monitor. Sometimes it launches successfully without all these symptoms.
What can be the reason for this? Is the latest version of the Emacs is buggy for mac or there is a different known reason for that?
